Tenryu PT-21040 8-1/4 x 40 T PT Series Carbide Tipped Blade, 5/8 Arbor, 7300 RPM The tremendously popular 8-1/4in Power Tool Series Blade. Works with both table and portable saws. ATB Alternate Top Bevel Tooth Geometry - Typical for cross-grain. Also used on ripping blades. Exceptional features and superior quality, Thin Kerf. BLADE FEATURES: Fully hardened, expertly tensioned tool steel bodies absorb impact, remain flat and true, and resist excess heat build-up. High-grade, C-3, fine-grain tungsten carbide tips resist erosion for extended blade life. Aggressive rake angles for maximum cutting speed and efficiency. Each tip is precision honed on all four exposed surfaces. This minimizes micro-chipping along the sharp edge of the blade and results in a sharper, longer-lasting edge. Thin kerf for less waste and lighter cutting performance reduced feed pressure. Inserted tooth design on some models greatly increases the body-to-tip braze area for greater support and tip strength. Expansion slots and/or variable pitch gullets keep blade cool under stressful work loads. Can be resharpened for extended blade life. 8-1/4in Diameter, 40 Teeth, 5/8in Arbor with Diamond Knockout, ATB Grind, 0.079in Kerf, 15 Rake
